Title: Manual opening/closing apparatus for valve
Inventor: KONNO SEIJI
IPC: F16K31/524
Filed: 1987-04-21
Abstract: PURPOSE:To simplify the structure of the apparatus in the caption, by providing such a way that a connecting shaft directly coupled to a valve shaft is driven rotationally in relation to a body and a wing fixed to the connecting shaft is made to be engaged therewith and driven by manual rotation of a threaded shaft. CONSTITUTION:A connecting shaft 14 is born rotatably on a body 10, and the rectangular shaft end of an output shaft 30 is inserted into the one end of a wing 15, and the rectangular shaft end of the connecting shaft 14 is inserted into the other end thereof. A threaded shaft 11 and a rod 13 are born rotatably to the body 10 in a state of holding the wing 15 therebetween. When the threaded shaft 11 is rotated in the direction wherein a piece 16 pushes the wing 15, a valve may be manually opened and closed because the connecting shaft 14 coupled directly to a valve shaft is rotated. Accordingly, the structure can be simplified in comparison with a conventional method in which a worm wheel, gears and the like are usually used.

Title: Sealing structure of electric equipment and the like
Inventor: NIWA TSUNEO
IPC: H05K7/20
Filed: 1988-04-19
Abstract: PURPOSE:To prevent the occurrence of cracks accompanying the use when the outer surface of a metallic component such as a yoke is sealed with a resin, by forming a film on the surface of the metal part in which thermal expansion occurs during the use by electrodeposition coating and sealing the metallic component with a thermosetting resin. CONSTITUTION:A film is formed on the surface of a metallic component 3 in which thermal expansion occurs during the use by electrodeposition coating. The metallic component 3 is sealed with a thermosetting resin. For example, An electrodeposition coating film is formed on the surface of a yoke 3 to which a coil bobbin 2 is assembled by cation electrodeposition coating. A coil 1 is wound around the bobbin 2. In the electrodeposition coating, an ordinary cation electrodeposition paint, in which an epoxy resin is a main resin and a block isocianate resin is added as a hardening agent is used. An amino group is introduced in the epoxy resin. After the coil 1 is assembled into the yoke 3, sealing is performed with an epoxy resin by the same method as a conventional method. Thus, a casing 4 is formed. In this way, adhesion between the sealing resin and the metal is improved by the action of the electrodeposition coating film, and the occurrence of cracks due to the heating of the coil and the like can be prevented.

Abstract: PURPOSE:To make a glow start easy and the stability of a ballast and a tube lamp circuit warrantable as well as to make a lamp glowable in safety with a simple choke type ballast, by connecting a capacitive element to the inductance ballast for glow starting. CONSTITUTION:Using, for example, an alumina luminous tube having a tube size of 7.4mm. in inner diameter and 83mm. in distance between electrodes, a high pressure sodium lamp of 360W sealing sodium 4.5mg, mercury 20mg and xenon 350 Torr inside is manufactured, while a series body consisting of a resistor 9 and a bimetal switch 10 is installed inside an outer tube in parallel with the luminous tube 8, in addition to the luminous tube 8. And, a ceramic conductor of 3,000pF is connected to a single choke type ballast 11 in parallel. Moreover, as xenon sealing pressure is high, a start auxiliary conductor 13, consisting of a molybdic wire (0.7mm. in diameter) impressed with one side electrode potential, is applied to the overall length of a tube. In this connection, to prevent the sodium from vanishing, the start auxiliary conductor 13 is connected to the electrode via a bimetal switch 14 to be opened by heat radiation out of the luminous tube 8 after lamp glowing.

IPC: F24F11/02
Filed: 1990-04-12
Abstract: PURPOSE:To detect the apace temperature during narrow space heating operation for preventing an abnormal rise in the temperature by a method wherein the temperature is detected by using a temperature detector mounted on a refrigerant pipe during warm air operation in which a heater is energized, and the detected temperature is compared with the preset temperature to control the power supply to the heater. CONSTITUTION:In warm air operation, a path to a cooled air blow port is closed by a damper. Next, a fan motor is operated to send air, and the temperature is detected by a pipe sensor 14 of a temperature detector 17 and compared with the preset temperature T by a comparator in a microcomputer 15. Power is supplied to a heater 10 via a relay circuit 19 of a controlled 20 and warm air operation is carried out. During warm air operation, a refrigerating cycle is out of operation and only air is sent to an evaporator, so that the blowing air temperature, that is, the room temperature can be detected by the pipe sensor 14. As a result, the space temperature is detected without an additional temperature detector during small space heating operation.
